Plus: Pink, Idina Menzel, Bette Midler, and an impromptu Darlene Love

Pharrell Williams kicked off the Oscars performances with a dancing-filled take on his “Happy (above), from Despicable Me 2 but also set for his solo album G I R L, out March 3. And yes: Although he’s donating the gazillion-gallon hat to charity, he was still sporting the Canadian mountie look. The hat came back around later so host Ellen DeGeneres could collect for the pizza she ordered mid-show.

Elsewhere, Pink — in a rare non-death-defying award show appearance — paid tribute to the 75th anniversary of The Wizard of Oz with “Somewhere Over the Rainbow,” and Bette Midler sang “The Wind Beneath My Wings” for the in-memoriam segment (which honored Philip Seymour Hoffman, among others lost this year). Although not officially billed as a performance, Darlene Love singing a cappella after 20 Feet From Stardom’s Best Documentary win also definitely belongs here.
